Ceramic laser materials have come a long way since the first demonstration of lasing in 1964. Improvements in powder synthesis and ceramic sintering as well as novel ideas have led to notable achievements. These include the first Nd:yttrium aluminum garnet (YAG) ceramic laser in 1995, breaking the 1 KW mark in 2002 and then the remarkable demonstration of more than 100 KW output power from a YAG ceramic laser system in 2009. Additional developments have included highly doped microchip lasers, ultrashort pulse lasers, novel materials such as sesquioxides, fluoride ceramic lasers, selenide ceramic lasers in the 2 to 3 μm region, composite ceramic lasers for better thermal management, and single crystal lasers derived from polycrystalline ceramics. This paper highlights some of these notable achievements.
自1964年首次实现激光发射以来，陶瓷激光材料已经取得了长足的发展。粉末合成和陶瓷烧结技术的改进以及新颖的理念带来了显著的成果。这些成果包括1995年首次研制出的钕：钇铝石榴石（YAG）陶瓷激光器，2002年突破1千瓦大关，随后在2009年YAG陶瓷激光系统实现了超过100千瓦的输出功率这一卓越表现。其他进展还包括高掺杂微芯片激光器、超短脉冲激光器、诸如倍半氧化物等新型材料、氟化物陶瓷激光器、2至3微米区域的硒化物陶瓷激光器、用于更好热管理的复合陶瓷激光器以及由多晶体制成的单晶激光器。本文重点介绍了其中一些显著成就。
